Application filed October 20, 1917. Serial No. 197,746.

To all whom t may concern:

Be it known that LEoNIDAs H. VAN SYGKLE, deceased, late of Fort Lee, inthe county of Bergen and State of New Jersey, did invent and produce anImprovement in 'lellurians, of which the following is a specificationthereof.

The invention relates to tellurians and improvements in the mechanicalmeans which, when operated, will impart a rotative and gyratory movementto a sphere adaptable to rotate upon an inclined axis, and at the sametime revolve around a fixed center. The invention is used to instructchildren in the various natural phenomena of the solar system, suoli asthe approximate movement of the earth as, rotating on its own axis, itrevolves around the sun, thus causing day and night, and the seasons; inthe relative position of the planets to the earth and sun; and toillustrate the fixed inclination of the axis of the earth to the planeof the earths orbit; the fixed general direction in which the axispoints and its relative positions to the sun during the earthsrevolution.

The construction shown in the patent dated February 23,V 1909; No.913,074: differs materially from that of the invention herein disclosed,as in the former the mechanism was too crude to be reliable whenoperated. The objections discovered in the former invention are obviatedby the invention herein disclosed, which consist of bars horizontallyarranged one above the other, each having one end thereof looselymounted upon fixed devices centrally located on the base of thestructure, the laterally extending` bars each having their outer endloosely mounted upon revoluble devices integral or otherwise connectedwith the prolongation of the axis whose extreme lower end is rotativelymounted upon, and near the end, of a movable, radially arranged arm,while the rearward end of said arm is loosely mounted upon thevertically fixed means centrally located, all of which will be fullydescribed and pointed out in the claims.

In the drawings, Figure l represents a side elevation of the telluriancomplete. In this view is shown the relative position of thehorizontally arranged bars and the revolving devices beneath the sphere,and the fixed devices centrally located on the base of the structure.

Fig. 2 is a plan view of Fig. l. ln this is provided with a verticalfixed spindle l) centrally located thereon. Upon the spindle Z1 isloosely mounted the radial swinging arm c and above this swinging arm cand integral with the spindle are two loops or bends d CZ arranged atright angles to each other and to that of' the vertically fixed spindleb, the latter of which also carries the small ball c which I term thesun, below the sun and above the loops or bends d-d is mounted thenon-rotative pulley f which carries the flexible cross belt g and iscarried upon the pulley 7b, secured fixedly to the sphere c', thelatter' loosely mounted upon the inclined axis which is provided withthe spherical body Z adapted to engage with a correspondingly shapedconcavity located on the base of the pulley t.

The inclined axis l.: beneath the pulley t terminates into two loops orbends m m arranged at right angles to each other and to that of thevertical axis a loosely mounted upon the radial swinging arm c.

The outer portions of the fixed loops or bends d--OZ are connected withthe revoluble loops or bends m m by means of the horizontally arrangedbars p p which are loosely mounted thereon.

It will be obvious that the said pulley It. is connected with thenon-rotatable pulley f mounted upon the centrally fixed spindle b,forming the axis of the radial arm c by means of the crossed flexiblebelt g. The distance between the non-rotatable pulley f and the pulley71, is kept constant by reason of the lower axial center of the pulley flying in the vert-ical alinement with the axis 7c at a, loosely mountedin the radial swinging arm c, thus maintaining at all times the samedistance between the driving edges of' the non-rotatable pulley and theinclined pulley 7L and keeping the tension of the flexible connectionconstant. 'lhe shorter or rearward portion of the radial swinging arm cis provided the hole c which is used by the instructor to insert hispencil or wand when desirous of operating the device. It

llO

will be obvious that the extreme end of the arm c is provided with theclip c2, a portion .thereof adapted to engage with the annular groove c3of the base a of the structure. The projections 5. 5. shown on thesphere t and connected by dotted lines is merely to indicate theantipodes.

Vhen the instructor desires to instruct his pupils in the relativeposition of the earth to the sun, and the manner of rotating about itsown axis while revolving around the sun, he will first place his pencilor wand in the depression c2 and move the arm c in the olirectionindicated by the arrow 6, thereby causing the flexible belt g to travelin the direction indicated by the arrows 7 and the loops m fm move asindicated by the arrows 8. 8.; the bars travel in the directionindicated by the arrows 9. 9., and the sphere i rotates upon the axis cin the direction indicated by the arrow 10.

The upper surface of the base a is divided i into four equal parts,representing the four seasons of the year. The longer portion of theradial swinging arm c lies directly over Vthe section or division markedl/Vinter which indicates the starting point from which the radialswinging arm travels in the directionv indicated by the arrow towardSpring, and so on until Winter is again reached, when the earth shallhave made one complete revolution around the sun.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent, is

1. In a tellurian, the combination consisting of an inclined axis, arevoluble vertical axis supporting said inclined axis and provided withloops integral or otherwise connected therewith, a fixed base, avertical axis formed with loops secured to said base, and meansconnecting corresponding loops of the vertical axes.

2. In a tellurian, the combination consisting of an inclined axis, arevoluble vertical axis supporting said inclined axis and provided withloops integral or otherwise connected therewith, a iixed vertical axisformed with loops, connection between corresponding loops on thevertical axes, a globe, a pulley fixedly connected therewith, the globeand pulley being mounted loosely upon the inclined axis aforesaid, anddriving means for said pulley.

In a tellurian, the combination consisting of an inclined axis, arevoluble vertical axis supporting the same, two revoluble loops securedto the vertical axis and arranged in dierent horizontal planes at rightangles to each other, a lixed vertical axis, loops integral therewith, aswinging arm carrying the aforesaid revoluble axis 'and parallel barsconnecting corresponding loops.

+L. In a 'tellin-ian, the combination consisting of an inclined axis, arevoluble vertical axis supporting said inclined axis and provided withloops integral therewith, a iixed vertical axis provided with loops,laterally arranged parallel bars loosely connected with said loops, anon-rotatable pulley ixedly mounted on said lixcd vertical axis, aglobe, and a rotatable pulley secured thereto, both mounted upon theinclined axis, a cross belt connecting said pulleys and an arm pivotedon said fixed axis and carrying said revoluble vertical axis.
